Why Your Solar Panels Sit Dark for Weeks After Install (Florida Interconnection & PTO)

Install day feels like the finish line. The crew leaves, the panels are gleaming, and you expect your meter to start spinning backward. Then nothing happens — for days, sometimes many weeks. Your system is legally not allowed to turn on yet, and the rep who promised "savings starting next month" has moved on to the next neighborhood. Here is what is actually happening and why it takes so long.

## The two gates after install: inspection and PTO

Between "panels installed" and "system producing," two approvals stand in the way:

1. **Local permit inspection (AHJ).** Your city or county building department (the Authority Having Jurisdiction) must inspect the installation for electrical and structural code compliance. The installer schedules it; municipal backlogs and failed first inspections add time.

2. **Permission to Operate (PTO) from your utility.** Even after the local inspection passes, your utility (FPL, Duke, TECO, OUC, etc.) must approve the interconnection and, often, swap in a bidirectional net meter before you are legally allowed to energize the system. **Turning it on before PTO can void agreements and create safety/liability issues.**

Only after PTO is granted can the system legally produce — and your net-metering credits begin.

## A realistic Florida timeline

| Stage | Typical range | |---|---| | Contract signed → permit approved | 2–6 weeks | | Permit → install day | 1–4 weeks | | Install → local inspection passed | 1–3 weeks | | Inspection → utility PTO + meter swap | 2–6 weeks | | **Total: signed → producing** | **6–16+ weeks** |

So "I''ll be saving money next month" is rarely true. Eight to twelve weeks from signature to switched-on is normal, and complex permits or utility backlogs push it further.

## Why this matters to your wallet

- **You may still be financing.** Many solar loans begin charging you before PTO — so you can be making a loan payment on a system that is producing zero. Ask exactly when payments start relative to PTO. - **The "savings" clock has not started.** Any payback math the salesperson showed assumes the system is on. Every week of PTO delay is a week of no savings but possibly a loan payment. - **Promised production guarantees** (if any) usually start at PTO, not install.

## Questions to ask before you sign

- "What is your **realistic** signed-to-PTO timeline for my utility and county — not the best case?" - "When does my **first loan payment** hit relative to PTO? Is there a payment-deferral until the system is energized?" - "Who handles the **inspection and PTO paperwork**, and what happens if it fails the first inspection?" - "Is there any **compensation** if PTO drags past a stated window?"

## How to protect yourself

- Get the timeline **in writing**, including who is responsible for each step. - If financing, push for **payment deferral until PTO** — reputable lenders offer it. - Keep the installer''s project-manager contact; the salesperson is not your post-sale support. - Do not let anyone tell you to "just flip it on" before PTO.

## FAQ

**Why can''t I turn my panels on right after install?** Because the local inspection and your utility''s Permission to Operate (PTO) are legally required first. Energizing before PTO can void agreements and is unsafe.

**Is a 10-week wait normal in Florida?** Yes. Six to sixteen weeks from contract to producing is common depending on county permitting speed and utility interconnection backlog.

**Will I owe loan payments before the system turns on?** Sometimes — it depends on the lender. Ask for payment deferral until PTO, and get the answer in writing before signing.
